The California High Speed Rail Authority’s decision to start construction on the bullet train in Central Valley ahead of finalizing its plans and obtaining land has led to $600 million in cost overrun, according to a report published Thursday by State Auditor Elaine Howle.

We get the latest on the audit, as well as what it means for the future of the bullet train in California.

We have reached out to the High Speed Rail Authority but they declined our request for an interview. We have also reached out the California State Auditor’s Office, but they could not provide someone in time for the interview.
